CryptoBox 0.3.2
The CryptoBox is a Debian/Linux based live-cd. more>>
The CryptoBox is a Debian/Linux based live-cd. CryptoBox CD boots up, starting a secure fileserver.
Even non-technical users are able to store their data on its encrypted harddisk. There is no special knowledge about cryptography or servers required at all.
The CryptoBox is fully controllable via your web browser.
Version 0.2 is fully usable and runs stable. From now on were just adding features and translations (atm english, german, slovenian).
Enhancements:
- Support for more than one hard disk was added.
- Manual partitioning is allowed.
- LUKS is used for hard disk encryption.
- Plaintext partitions are supported.
- The time and date can be changed.
- Flexible feature management was implemented to enable and disable specific plugins.
- Prepared RAID partitions are used.

Contact Book 1.0
Contact Book is a simple contact book manager. more>>
Contact Book is a simple contact book manager.
Simple Contact that could be compared to Mac OS Xs simply address book application. I plan on making the initial release with very basic functionality but it will certainly grow from there.
Although it is in a deb it does net check dependancies so make sure you have mono, GTK# (2.4), and sqlite installed to use it.
Why you might be interested:
- Simple Address Book so you dont have to use evolution (this was my main reason for starting this project)
- Easy to use (not pop up dialog boxes)

Crypt::UnixCrypt 1.0
Crypt::UnixCrypt is a perl-only implementation of the crypt function. more>>
Crypt::UnixCrypt is a perl-only implementation of the crypt function.
SYNOPSIS
use Crypt::UnixCrypt;
$hashed = crypt($plaintext,$salt);
# always use this modules crypt
BEGIN { $Crypt::UnixCrpyt::OVERRIDE_BUILTIN = 1 }
use Crypt::UnixCrypt;
This module is for all those poor souls whose perl port answers to the use of crypt() with the message `The crypt() function is unimplemented due to excessive paranoia..
This module wont overload a built-in crypt() unless forced by a true value of the variable $Crypt::UnixCrypt::OVERRIDE_BUILTIN.
If you use this module, you probably neither have a built-in crypt() function nor a crypt(3) manpage; so Ill supply the appropriate portions of its description (from my Linux system) here:
crypt is the password encryption function. It is based on the Data Encryption Standard algorithm with variations intended (among other things) to discourage use of hardware implementations of a key search.
$plaintext is a users typed password.
$salt is a two-character string chosen from the set [a-zA-Z0-9./]. This string is used to perturb the algorithm in one of 4096 different ways.
By taking the lowest 7 bit of each character of $plaintext (filling it up to 8 characters with zeros, if needed), a 56-bit key is obtained. This 56-bit key is used to encrypt repeatedly a constant string (usually a string consisting of all zeros). The returned value points to the encrypted password, a series of 13 printable ASCII characters (the first two characters represent the salt itself).
Warning: The key space consists of 2**56 equal 7.2e16 possible values. Exhaustive searches of this key space are possible using massively parallel computers. Software, such as crack(1), is available which will search the portion of this key space that is generally used by humans for passwords. Hence, password selection should, at minimum, avoid common words and names. The use of a passwd(1) program that checks for crackable passwords during the selection process is recommended.
The DES algorithm itself has a few quirks which make the use of the crypt(3) interface a very poor choice for anything other than password authentication. If you are planning on using the crypt(3) interface for a cryptography project, dont do it: get a good book on encryption and one of the widely available DES libraries.

Trfcrypt 1.2
Trfcrypt is an add-on package to the tcl-extension trf. more>>
trfcrypt is an add-on package to the tcl-extension trf. It provides the encryption functionality which was removed from the base package to allow its inclusion on the Tcl/Tk CDROM without violating US export control laws on cryptography.
The C API is layered on top of the trf C API and provides a set of commands for the management, implementation and usage of blockciphers and stream.
Although it is possible to implement ciphers using only the trf C API the code in this package makes it much easier, as general things like the handling of blockcipher modes are done here, thus obviating the need to reimplement them every time. A new cipher just has to provide some information about itself (key sizes) and functions to:
- generate the internal keyschedule from the specified key
- encrypt/decrypt a character or a block of data

autocrypt 0.0.3
autocrypt is an automatic crypted disk mapping creation with rootplug. more>>
autocrypt its a set of scripts that use linux hotplug/udev/cryptoapi mechanism to allow you autocrypting a harddrive what do I means by autocrypting : I means using a "rootplug" ie an identification device to activate the possibility of mounting automatically a crypted device.
Youll need such tool if typically you have some data you require to protect whith cryptography and that you want not creating the node "by hand" each time (this require root privileges) look at the following scenario :
you work into a company which data are sensitives
you dont want to encrypt your home using pam crypt because
you dont want to have to setup your workspace each time you come back.
So you dant want to logout, using a screensaver to prevent use of your computer. But while youre loged the data are accessible.... a malicious hacker can login to you box via network and have access to your data....
You can manually create the cryting device mounting and umounting them at demand but this means you have root privilege you can use a special identification device, a "key" that do it for you.... thats autocrypt this solution use the widely available usbkeys/drives to create the unencrypted devices when the key is pluged and to remove it safely when the device is removed.

<<lessLibTomCrypt is a fairly comprehensive, modular and portable cryptographic toolkit that provides developers with a vast array of well known published block ciphers, one-way hash functions, chaining modes, pseudo-random number generators, public key cryptography and a plethora of other routines.
LibTomCrypt has been designed from the ground up to be very simple to use. It has a modular and standard API that allows new ciphers, hashes and PRNGs to be added or removed without change to the overall end application. It features easy to use functions and a complete user manual which has many source snippet examples.
LibTomCrypt is free for all purposes under the public domain. This includes commercial use, redistribution and even branching.
Main features:
- Public domain and open source.
- Written entirely in portable ISO C source (except for things like RNGs for natural reasons)
- Builds out of the box on virtually every box. All that is required is GCC for the source to build.
- Includes a 90+ page user manual in PDF format (with working examples in it)
- Block Ciphers
- Ciphers come with an ECB encrypt/decrypt, setkey and self-test interfaces.
- All ciphers have the same prototype which facilitates using multiple ciphers at runtime.
- Some of the ciphers are flexible in terms of code size and memory usage.
- Ciphers Supported.
